HOW TO DETERMINE PCV (PACKED CELL VOLUME)

The Packed Cell Volume (PCV) Test 1. Objective: This is one of the oldest tests done in medical practice. The objective of this test was to determine the percentage of red blood cells (RBCs) in whole blood. It  also helped to assess the blood’s capacity to carry oxygen. ________________________________________ 2. Principle: The test was based on the principle that when blood was centrifuged, the red blood cells settled at the bottom of the tube, forming a packed column. The ratio of the packed RBC column to the total blood column gave the packed cell volume (PCV), expressed as a percentage. ________________________________________ 3. Materials: • Microhematocrit capillary tubes • Microhematocrit centrifuge • Plasticine or sealing clay • Microhematocrit reader • Lancet • Alcohol swab • Cotton ________________________________________ 4. Procedure (Microhematocrit Method): 1. The fingertip was cleaned with an alcohol swab and pricked with a sterile lancet. 2. Blood was collected into ...

WHAT IS THE BEST DIET TO LOWER CHOLESTEROL AND LOSE WEIGHT?

WHAT IS THE BEST DIET TO LOWER CHOLESTEROL AND LOSE WEIGHT? According to research studies, eating a Mediterranean diet can help you to lower various risk factors for cardiovascular disease, including cholesterol levels.  This diet mainly includes a lot of vegetables, fruits, legumes, nuts, olive oil, whole grain products, fish, and poultry. Reduce consumption of processed foods, which are high in trans fat, which in turn contribute to the high serum cholesterol levels. A change in diet may just be able to; clean out the plaque buildup in your arteries, drop your cholesterol to a healthy and balanced level, and enhance your physical and psychological energy to levels you did not think possible.

THINGS YOU SHOULD KNOW ABOUT USING A CONDOM

THINGS YOU SHOULD KNOW ABOUT USING A CONDOM You should be aware of these dos and don'ts on how to use a condom during sex. 1.Hold the condom tip between your finger and thumb to ensure it's on correctly and there's no air trapped inside (the condom may split if the air is trapped inside). Put the condom over your penis. Roll the condom down the length of your erect penis while squeezing the tip of the condom. 2.You should be aware that when putting on a condom, it is critical to squeeze the tip to remove any air. Otherwise, the condom will likely break. 3.It is a good idea to use lubricant, but make sure it is water-based (such as K.Y. Jelly or Durex Play). Other products, particularly those that aren't intended for sex, such as Vaseline, are often oil-based and can eat into condoms, causing them to break. 4.It is critical to use the correct sized condom. Too big and it will slip off, too small and it will tear. Condoms come in a variety of sizes, so you should be ab...

HOW TO CLEAN YOUR EARS;AND HOW NOT TO

HOW TO CLEAN YOUR EARS; AND HOW NOT TO Use of cotton buds on the ears Should be discouraged If your problem isn’t serious, but you do feel like you have too much earwax buildup, you can gently clean the outside of your ears.  It could be as simple as using a washcloth. You also can try putting a few drops of baby oil, hydrogen peroxide, mineral oil, or glycerin in your ear to soften the wax. Or you can use an over-the-counter wax removal kit. Besides cotton swabs or any other small or pointy objects, don't use ear candles to clean your ears.  Studies show they’re not effective and they can even cause injury.  The reason we feel tempted to clean our ears is because of a substance called cerumen, commonly referred to as earwax. It is natural for your body to produce it, and it protects and lubricates your ears. Your ears would be itchy and dry if you didn't have earwax. The cerumen even has antibacterial properties, which means your ears will clean themselves. Earwax acts a...

HOW TO CARE FOR YOUR VAGINA: AND WHAT NOT TO DO

HOW TO CARE FOR YOUR VAGINA: AND WHAT NOT TO DO To begin, it's important to recognize that the vagina is a self-cleaning organ that does not require special cleaning products. It doesn't even require any cleaning products! Using douches or similar products to clean the vagina can cause inflammation and change the pH of the vagina. Douching is one of these ostensibly cleaning activities. Douching is the process of cleaning or washing out the vagina with water or a combination of other fluids such as H2O plus vinegar, baking soda, or iodine. If there is a bad vaginal odor, possibly due to an infection, the douching will only mask the smell and the underlying problem will remain. A complex colony of beneficial bacteria and other microbes helps keep the vagina healthy. Washing, especially with harsh soaps or douches, can throw the vaginal pH out of balance, increasing the risk of infections and unpleasant odors. Washing, particularly with harsh soaps or douches, can destabilize the...
